-- | Perform an action after the current mouse drag is completed.
module XMonad.Actions.AfterDrag

-- | Schedule a task to take place after the current dragging is completed.
afterDrag :: X () -> X ()

-- | Take an action if the current dragging can be considered a click,
--   supposing the drag just started before this function is called. A drag
--   is considered a click if it is completed within 300 ms.
ifClick :: X () -> X ()

-- | Take an action if the current dragging is completed within a certain
--   time (in milliseconds.)
ifClick' :: Int -> X () -> X () -> X ()


-- | Lets you constrain the aspect ratio of a floating window (by, say,
--   holding shift while you resize).
--   
--   Useful for making a nice circular XClock window.
module XMonad.Actions.ConstrainedResize

-- | Resize (floating) window with optional aspect ratio constraints.
mouseResizeWindow :: Window -> Bool -> X ()


-- | Provides bindings to cycle through most recently used workspaces with
--   repeated presses of a single key (as long as modifier key is held
--   down). This is similar to how many window managers handle window
--   switching.
module XMonad.Actions.CycleRecentWS

-- | Cycle through most recent workspaces with repeated presses of a key,
--   while a modifier key is held down. The recency of workspaces previewed
--   while browsing to the target workspace is not affected. That way a
--   stack of most recently used workspaces is maintained, similarly to how
--   many window managers handle window switching. For best effects use the
--   same modkey+key combination as the one used to invoke this action.
cycleRecentWS :: [KeySym] -> KeySym -> KeySym -> X ()

-- | Cycle through a finite list of WindowSets with repeated presses of a
--   key, while a modifier key is held down. For best effects use the same
--   modkey+key combination as the one used to invoke this action.
cycleWindowSets :: (WindowSet -> [WindowSet]) -> [KeySym] -> KeySym -> KeySym -> X ()


-- | This module provides a method to cease management of a window without
--   unmapping it. This is especially useful for applications like kicker
--   and gnome-panel. See also <a>XMonad.Hooks.ManageDocks</a> for more a
--   more automated solution.
--   
--   To make a panel display correctly with xmonad:
--   
--   <ul>
--   <li>Determine the pixel size of the panel, add that value to
--   <a>defaultGaps</a></li>
--   <li>Launch the panel</li>
--   <li>Give the panel window focus, then press <tt>mod-d</tt> (or
--   whatever key you have bound <a>demanage</a> to)</li>
--   <li>Convince the panel to move/resize to the correct location.
--   Changing the panel's position setting several times seems to
--   work.</li>
--   </ul>
module XMonad.Actions.DeManage

-- | Stop managing the currently focused window.
demanage :: Window -> X ()


-- | Dwm-like swap function for xmonad.
--   
--   Swaps focused window with the master window. If focus is in the
--   master, swap it with the next window in the stack. Focus stays in the
--   master.
module XMonad.Actions.DwmPromote

-- | Swap the focused window with the master window. If focus is in the
--   master, swap it with the next window in the stack. Focus stays in the
--   master.
dwmpromote :: X ()


-- | Find an empty workspace.
module XMonad.Actions.FindEmptyWorkspace

-- | Find and view an empty workspace. Do nothing if all workspaces are in
--   use.

--   all workspaces are in use.
tagToEmptyWorkspace :: X ()

-- | Send current window to an empty workspace. Do nothing if all
--   workspaces are in use.
sendToEmptyWorkspace :: X ()


-- | Move and resize floating windows without warping the mouse.
module XMonad.Actions.FlexibleManipulate

-- | Given an interpolation function, implement an appropriate window
--   manipulation action.
mouseWindow :: (Double -> Double) -> Window -> X ()

-- | Manipulate the window based on discrete pick regions; the window is
--   divided into regions by thirds along each axis.
discrete :: Double -> Double

-- | Scale/reposition the window by factors obtained from the mouse
--   position by linear interpolation. Dragging precisely on a corner
--   resizes that corner; dragging precisely in the middle moves the window
--   without resizing; anything else is an interpolation between the two.
linear :: Double -> Double

-- | Only resize the window, based on the window quadrant the mouse is in.
resize :: Double -> Double

-- | Only reposition the window.
position :: Double -> Double


-- | Move and resize floating windows.
module XMonad.Actions.FloatKeys

-- | <tt>keysMoveWindow (dx, dy)</tt> moves the window by <tt>dx</tt>
--   pixels to the right and <tt>dy</tt> pixels down.
keysMoveWindow :: D -> Window -> X ()

-- | <tt>keysMoveWindowTo (x, y) (gx, gy)</tt> moves the window relative
--   point <tt>(gx, gy)</tt> to the point <tt>(x,y)</tt>, where
--   <tt>(gx,gy)</tt> gives a position relative to the window border, i.e.
--   <tt>gx = 0</tt> is the left border, <tt>gx = 1</tt> is the right
--   border, <tt>gy = 0</tt> is the top border, and <tt>gy = 1</tt> the
--   bottom border.
--   
--   For example, on a 1024x768 screen:
--   
--   <pre>
--   keysMoveWindowTo (512,384) (1%2, 1%2) -- center the window on screen
--   keysMoveWindowTo (1024,0) (1, 0)      -- put window in the top right corner
--   </pre>
keysMoveWindowTo :: P -> G -> Window -> X ()

-- | <tt>keysResizeWindow (dx, dy) (gx, gy)</tt> changes the width by
--   <tt>dx</tt> and the height by <tt>dy</tt>, leaving the window-relative
--   point <tt>(gx, gy)</tt> fixed.
--   
--   For example:
--   
--   <pre>
--   keysResizeWindow (10, 0) (0, 0)      -- make the window 10 pixels larger to the right
--   keysResizeWindow (10, 0) (0, 1%2)    -- does the same, unless sizeHints are applied
--   keysResizeWindow (10, 10) (1%2, 1%2) -- add 5 pixels on each side
--   keysResizeWindow (-10, -10) (0, 1)   -- shrink the window in direction of the bottom-left corner
--   </pre>
keysResizeWindow :: D -> G -> Window -> X ()

-- | <tt>keysAbsResizeWindow (dx, dy) (ax, ay)</tt> changes the width by
--   <tt>dx</tt> and the height by <tt>dy</tt>, leaving the screen absolute
--   point <tt>(ax, ay)</tt> fixed.
--   
--   For example:
--   
--   <pre>
--   keysAbsResizeWindow (10, 10) (0, 0)   -- enlarge the window; if it is not in the top-left corner it will also be moved down and to the right.
--   </pre>
keysAbsResizeWindow :: D -> D -> Window -> X ()
type P = (Position, Position)
type G = (Rational, Rational)


-- | Focus the nth window of the current workspace.
module XMonad.Actions.FocusNth

-- | Give focus to the nth window of the current workspace.

--   if the message was handled, <tt>False</tt> otherwise. This function is

--   (using <a>sendSomeMessageWithNoRefreshToCurrentB</a>) and collect the
--   results. If any message was handled, refresh. If you want to sequence

-- | Variant of <a>sendSomeMessagesB</a> that discards the results.

--   xmonad-contrib library, see <a>XMonad.Doc.Extending</a>.
module XMonad.Doc.Configuring


-- | This module gives a brief overview of the xmonad internals. It is
--   intended for advanced users who are curious about the xmonad source
--   code and want an brief overview. This document may also be helpful for
--   the beginner/intermediate Haskell programmer who is motivated to write
--   an xmonad extension as a way to deepen her understanding of this
--   powerful functional language; however, there is not space here to go
--   into much detail. For a more comprehensive document covering some of
--   the same material in more depth, see the guided tour of the xmonad
--   source on the xmonad wiki:
--   <a>http://haskell.org/haskellwiki/Xmonad/Guided_tour_of_the_xmonad_source</a>.
--   
--   If you write an extension module and think it may be useful for
--   others, consider releasing it. Coding guidelines and licensing
--   policies are covered at the end of this document, and must be followed
--   if you want your code to be included in the official repositories. For
--   a basic tutorial on the nuts and bolts of developing a new extension
--   for xmonad, see the tutorial on the wiki:
--   <a>http://haskell.org/haskellwiki/Xmonad/xmonad_development_tutorial</a>.
module XMonad.Doc.Developing


-- | This module documents the xmonad-contrib library and how to use it to
--   extend the capabilities of xmonad.
--   
--   Reading this document should not require a deep knowledge of Haskell;
--   the examples are intended to be useful and understandable for those
--   users who do not know Haskell and don't want to have to learn it just
--   to configure xmonad. You should be able to get by just fine by
--   ignoring anything you don't understand and using the provided examples
--   as templates. However, relevant Haskell features are discussed when
--   appropriate, so this document will hopefully be useful for more
--   advanced Haskell users as well.
--   
--   Those wishing to be totally hardcore and develop their own xmonad
--   extensions (it's easier than it sounds, we promise!) should read the
--   documentation in <a>XMonad.Doc.Developing</a>.
--

module XMonad.Doc


-- | A debugging module to track key events, useful when you can't tell

-- | Module to apply a ManageHook to an already-mapped window when a
--   property changes. This would commonly be used to match browser windows
--   by title, since the final title will only be set after (a) the window
--   is mapped, (b) its document has been loaded, (c) all load-time scripts
--   have run. (Don't blame browsers for this; it's inherent in HTML and
--   the DOM. And changing title dynamically is explicitly permitted by
--   ICCCM and EWMH; you don't really want to have your editor window
--   umapped/remapped to show the current document and modified state in
--   the titlebar, do you?)
--   
--   This is a handleEventHook that triggers on a PropertyChange event. It
--   currently ignores properties being removed, in part because you can't
--   do anything useful in a ManageHook involving nonexistence of a
--   property.
module XMonad.Hooks.DynamicProperty

-- | Run a <a>ManageHook</a> when a specific property is changed on a
--   window. Note that this will run on any window which changes the

--   dynamicPropertyChange <a>WM_NAME</a> (className =? <a>Iceweasel</a>
--   <a>&amp;&amp;</a> title =? "whatever" --&gt; doShift "2")

--   Note that the fixity of (--&gt;) won't allow it to be mixed with ($),
--   so you can't use the obvious $ shorthand.
--   
--   <pre>
--   dynamicPropertyChange "WM_NAME" $ title =? "Foo" --&gt; doFloat -- won't work!
--   </pre>
--

modifyLayout :: (LayoutModifier m a, LayoutClass l a) => m a -> Workspace WorkspaceId (l a) a -> Rectangle -> X ([(a, Rectangle)], Maybe (l a))

-- | Similar to <a>modifyLayout</a>, but this function also allows you
--   update the state of your layout modifier(the second value in the outer
--   tuple).
--   
--   If both <a>modifyLayoutWithUpdate</a> and <a>redoLayout</a> return a
--   modified state of the layout modifier, <a>redoLayout</a> takes
--   precedence. If this function returns a modified state, this state will
--   internally be used in the subsequent call to <a>redoLayout</a> as
--   well.
modifyLayoutWithUpdate :: (LayoutModifier m a, LayoutClass l a) => m a -> Workspace WorkspaceId (l a) a -> Rectangle -> X (([(a, Rectangle)], Maybe (l a)), Maybe (m a))

-- | <a>handleMess</a> allows you to spy on messages to the underlying
--   layout, in order to have an effect in the X monad, or alter the layout
--   modifier state in some way (by returning <tt>Just nm</tt>, where
--   <tt>nm</tt> is a new modifier). In all cases, the underlying layout
--   will also receive the message as usual, after the message has been
--   processed by <a>handleMess</a>.
--   
--   If you wish to possibly modify a message before it reaches the
--   underlying layout, you should use <a>handleMessOrMaybeModifyIt</a>
--   instead. If you do not need to modify messages or have access to the X
--   monad, you should use <a>pureMess</a> instead.
--   
--   The default implementation of <a>handleMess</a> calls <a>unhook</a>
--   when receiving a <a>Hide</a> or <a>ReleaseResources</a> method (after
--   which it returns <tt>Nothing</tt>), and otherwise passes the message
--   on to <a>pureMess</a>.
handleMess :: LayoutModifier m a => m a -> SomeMessage -> X (Maybe (m a))

-- | <a>handleMessOrMaybeModifyIt</a> allows you to intercept messages sent

--   alter the layout modifier state, or produce a modified message to be
--   passed on to the underlying layout.
--   
--   The default implementation of <a>handleMessOrMaybeModifyIt</a> simply
--   passes on the message to <a>handleMess</a>.
handleMessOrMaybeModifyIt :: LayoutModifier m a => m a -> SomeMessage -> X (Maybe (Either (m a) SomeMessage))

-- | <a>pureMess</a> allows you to spy on messages sent to the underlying
--   layout, in order to possibly change the layout modifier state.
--   
--   The default implementation of <a>pureMess</a> ignores messages sent to
--   it, and returns <tt>Nothing</tt> (causing the layout modifier to
--   remain unchanged).
pureMess :: LayoutModifier m a => m a -> SomeMessage -> Maybe (m a)

-- | <a>redoLayout</a> allows you to intercept a call to <a>runLayout</a>
--   on workspaces with at least one window, <i>after</i> it is called on
--   the underlying layout, in order to perform some effect in the X monad,
--   possibly return a new layout modifier, and/or modify the results of
--   <a>runLayout</a> before returning them.
--   
--   If you don't need access to the X monad, use <a>pureModifier</a>
--   instead. Also, if the behavior you need can be cleanly separated into
--   an effect in the X monad, followed by a pure transformation of the
--   results of <a>runLayout</a>, you should consider implementing
--   <a>hook</a> and <a>pureModifier</a> instead of <a>redoLayout</a>.
--   
--   On empty workspaces, the Stack is Nothing.
--   
--   The default implementation of <a>redoLayout</a> calls <a>hook</a> and
--   then <a>pureModifier</a>.
redoLayout :: LayoutModifier m a => m a -> Rectangle -> Maybe (Stack a) -> [(a, Rectangle)] -> X ([(a, Rectangle)], Maybe (m a))

-- | <a>pureModifier</a> allows you to intercept a call to <a>runLayout</a>
--   <i>after</i> it is called on the underlying layout, in order to modify
--   the list of window/rectangle pairings it has returned, and/or return a
--   new layout modifier.
--   
--   The default implementation of <a>pureModifier</a> returns the window
--   rectangles unmodified.
pureModifier :: LayoutModifier m a => m a -> Rectangle -> Maybe (Stack a) -> [(a, Rectangle)] -> ([(a, Rectangle)], Maybe (m a))

-- | <a>hook</a> is called by the default implementation of
--   <a>redoLayout</a>, and as such represents an X action which is to be
--   run each time <a>runLayout</a> is called on the underlying layout,
--   <i>after</i> <a>runLayout</a> has completed. Of course, if you
--   override <a>redoLayout</a>, then <a>hook</a> will not be called unless
--   you explicitly call it.
--   
--   The default implementation of <a>hook</a> is <tt>return ()</tt> (i.e.,
--   it has no effect).
hook :: LayoutModifier m a => m a -> X ()

-- | <a>unhook</a> is called by the default implementation of
--   <a>handleMess</a> upon receiving a <a>Hide</a> or a
--   <a>ReleaseResources</a> message.
--   
--   The default implementation, of course, does nothing.
unhook :: LayoutModifier m a => m a -> X ()

-- | <a>modifierDescription</a> is used to give a String description to
--   this layout modifier. It is the empty string by default; you should
--   only override this if it is important that the presence of the layout
--   modifier be displayed in text representations of the layout (for
--   example, in the status bar of a <a>XMonad.Hooks.DynamicLog</a> user).
modifierDescription :: LayoutModifier m a => m a -> String

-- | <a>modifyDescription</a> gives a String description for the entire
--   layout (modifier + underlying layout). By default, it is derived from
--   the concatenation of the <a>modifierDescription</a> with the
--   <a>description</a> of the underlying layout, with a "smart space" in
--   between (the space is not included if the <a>modifierDescription</a>
--   is empty).
modifyDescription :: (LayoutModifier m a, LayoutClass l a) => m a -> l a -> String

-- | A <a>ModifiedLayout</a> is simply a container for a layout modifier

--   
--   This overrides the previous definition of mod-m.
--   
--   Note that, unlike in xmonad 0.4 and previous, you can't use modMask to
--   refer to the modMask you configured earlier. You must specify mod1Mask
--   (or whichever), or add your own <tt>myModMask = mod1Mask</tt> line.

--   main = xmonad $ def { terminal = "urxvt" }

removeKeysP :: XConfig l -> [String] -> XConfig l

additionalMouseBindings :: XConfig a -> [((ButtonMask, Button), Window -> X ())] -> XConfig a

-- | Like <a>removeKeys</a>, but for mouse bindings.
removeMouseBindings :: XConfig a -> [(ButtonMask, Button)] -> XConfig a

-- | Given a config (used to determine the proper modifier key to use) and
--   a list of <tt>(String, X ())</tt> pairs, create a key map by parsing
--   the key sequence descriptions contained in the Strings. The key
--   sequence descriptions are "emacs-style": <tt>M-</tt>, <tt>C-</tt>,
--   <tt>S-</tt>, and <tt>M#-</tt> denote mod, control, shift, and
--   mod1-mod5 (where <tt>#</tt> is replaced by the appropriate number)
--   respectively. Note that if you want to make a keybinding using 'alt'
--   even though you use a different key (like the 'windows' key) for
--   'mod', you can use something like <tt>"M1-x"</tt> for alt+x (check the
--   output of <tt>xmodmap</tt> to see which mod key 'alt' is bound to).
--   Some special keys can also be specified by enclosing their name in
--   angle brackets.
--   
--   For example, <tt>"M-C-x"</tt> denotes mod+ctrl+x;
--   <tt>"S-&lt;Escape&gt;"</tt> denotes shift-escape;
--   <tt>"M1-C-&lt;Delete&gt;"</tt> denotes alt+ctrl+delete (assuming alt
--   is bound to mod1, which is common).
--   
--   Sequences of keys can also be specified by separating the key
--   descriptions with spaces. For example, <tt>"M-x y &lt;Down&gt;"</tt>
--   denotes the sequence of keys mod+x, y, down. Submaps (see
--   <a>XMonad.Actions.Submap</a>) will be automatically generated to
--   correctly handle these cases.
--   
--   So, for example, a complete key map might be specified as
--   
--   <pre>
--   keys = \c -&gt; mkKeymap c $
--       [ ("M-S-&lt;Return&gt;", spawn $ terminal c)
--       , ("M-x w", spawn "xmessage 'woohoo!'")  -- type mod+x then w to pop up 'woohoo!'
--       , ("M-x y", spawn "xmessage 'yay!'")     -- type mod+x then y to pop up 'yay!'
--       , ("M-S-c", kill)
--       ]
--   </pre>
--   
--   Alternatively, you can use <a>additionalKeysP</a> to automatically
--   create a keymap and add it to your config.
--   
--   Here is a complete list of supported special keys. Note that a few
--   keys, such as the arrow keys, have synonyms. If there are other
--   special keys you would like to see supported, feel free to submit a
--   patch, or ask on the xmonad mailing list; adding special keys is quite
--   simple.

mkKeymap :: XConfig l -> [(String, X ())] -> Map (KeyMask, KeySym) (X ())

-- | Given a configuration record and a list of (key sequence description,
--   action) pairs, check the key sequence descriptions for validity, and
--   warn the user (via a popup xmessage window) of any unparseable or
--   duplicate key sequences. This function is appropriate for adding to
--   your <tt>startupHook</tt>, and you are highly encouraged to do so;
--   otherwise, duplicate or unparseable keybindings will be silently
--   ignored.
--   
--   For example, you might do something like this:
--   
--   <pre>
--   main = xmonad $ myConfig
--   
--   myKeymap = [("S-M-c", kill), ...]
--   myConfig = def {

--       startupHook = return () &gt;&gt; checkKeymap myConfig myKeymap

--   }
--   </pre>
--   
--   NOTE: the <tt>return ()</tt> in the example above is very important!
--   Otherwise, you might run into problems with infinite mutual recursion:
--   the definition of myConfig depends on the definition of startupHook,
--   which depends on the definition of myConfig, ... and so on. Actually,
--   it's likely that the above example in particular would be OK without
--   the <tt>return ()</tt>, but making <tt>myKeymap</tt> take
--   <tt>myConfig</tt> as a parameter would definitely lead to problems.
--   Believe me. It, uh, happened to my friend. In... a dream. Yeah. In any
--   event, the <tt>return () &gt;&gt;</tt> introduces enough laziness to
--   break the deadlock.

-- | This is a draft of a brand new config syntax for xmonad. It aims to

--   It's brand new, so it's pretty much guaranteed to break or change

--   logs you out? It probably won't do that. Give it a try.

--   <ol>
--   <li>If any entry is the empty string, it'll be replaced with the

wsNames :: Settable [String] WorkspaceConfig

-- | The list of workspace keys. These are combined with the modifiers in

wsKeys :: Summable [String] [String] WorkspaceConfig

-- | Mapping from key prefix to command. Its type is <tt>[(String, String

sKeys :: Summable [String] [String] ScreenConfig

-- | Mapping from key prefix to command. Its type is <tt>[(String, ScreenId

--   different function type.
--   
--   Default:
--   
--   <pre>
--   [("M-", windows . onScreens W.view),
--    ("M-S-", windows . onScreens W.shift)]
--   </pre>
sActions :: Summable [(String, ScreenId -> X ())] [(String, ScreenId -> X ())] ScreenConfig

-- | Converts a stackset transformer parameterized on the workspace type
--   into one parameterized on the screen type. For example, you can use

--   acts as an identity function.

-- | Add a layout to the list of layouts choosable with mod-space. For

--   <pre>
--   resetLayout $ Tall 1 (3/100) (1/2) ||| Full
--   </pre>
--   
--   (The dollar is like an auto-closing parenthesis, so all the stuff to
--   the right of it is treated like an argument to resetLayout.)
resetLayout :: LayoutClass r Window => r Window -> Prime l r

-- | Modify your <tt>layoutHook</tt> with some wrapper function. You

--     modifyLayout smartBorders

modifyLayout :: LayoutClass r Window => (l Window -> r Window) -> Prime l r

--   Why do both <a>readsPrec</a> and <a>readPrec</a> exist, and why does
--   GHC opt to implement <a>readPrec</a> in derived <a>Read</a> instances
--   instead of <a>readsPrec</a>? The reason is that <a>readsPrec</a> is
--   based on the <a>ReadS</a> type, and although <a>ReadS</a> is mentioned
--   in the Haskell 2010 Report, it is not a very efficient parser data
--   structure.
--   
--   <a>readPrec</a>, on the other hand, is based on a much more efficient
--   <a>ReadPrec</a> datatype (a.k.a "new-style parsers"), but its
--   definition relies on the use of the <tt>RankNTypes</tt> language
--   extension. Therefore, <a>readPrec</a> (and its cousin,
--   <a>readListPrec</a>) are marked as GHC-only. Nevertheless, it is
--   recommended to use <a>readPrec</a> instead of <a>readsPrec</a>
--   whenever possible for the efficiency improvements it brings.
--   
--   As mentioned above, derived <a>Read</a> instances in GHC will
--   implement <a>readPrec</a> instead of <a>readsPrec</a>. The default
--   implementations of <a>readsPrec</a> (and its cousin, <a>readList</a>)
--   will simply use <a>readPrec</a> under the hood. If you are writing a
--   <a>Read</a> instance by hand, it is recommended to write it like so:
--   
--   <pre>
--   instance <a>Read</a> T where
--     <a>readPrec</a>     = ...
--     <a>readListPrec</a> = <a>readListPrecDefault</a>

--   Derived instances of <a>Show</a> have the following properties, which

--   
--   <ul>
--   <li>The result of <a>show</a> is a syntactically correct Haskell
--   expression containing only constants, given the fixity declarations in
--   force at the point where the type is declared. It contains only the
--   constructor names defined in the data type, parentheses, and spaces.
--   When labelled constructor fields are used, braces, commas, field
--   names, and equal signs are also used.</li>
--   <li>If the constructor is defined to be an infix operator, then
--   <a>showsPrec</a> will produce infix applications of the
--   constructor.</li>
--   <li>the representation will be enclosed in parentheses if the
--   precedence of the top-level constructor in <tt>x</tt> is less than
--   <tt>d</tt> (associativity is ignored). Thus, if <tt>d</tt> is
--   <tt>0</tt> then the result is never surrounded in parentheses; if
--   <tt>d</tt> is <tt>11</tt> it is always surrounded in parentheses,
--   unless it is an atomic expression.</li>
--   <li>If the constructor is defined using record syntax, then
--   <a>show</a> will produce the record-syntax form, with the fields given
--   in the same order as the original declaration.</li>
--   </ul>
--   
--   For example, given the declarations
--   
--   <pre>
--   infixr 5 :^:
--   data Tree a =  Leaf a  |  Tree a :^: Tree a
--   </pre>
--   
--   the derived instance of <a>Show</a> is equivalent to

--   <ul>

--   </ul>
--   
--   The other methods have the following default definitions, which may be

--   <pre>
--   forall x y. p (q x y) = f x . g y

--   
--   it follows from the above that

-- | Unlike the opaque <tt>IO</tt> actions that <tt>X</tt> actions can
--   wrap, regular reads from the <a>XConf</a> and modifications to the
--   <a>XState</a> are fundamentally pure—contrary to the current treatment
--   of such actions in most xmonad code. Pure modifications to the
--   <a>WindowSet</a> can be readily composed, but due to the need for
--   those modifications to be properly handled by <a>windows</a>, other
--   pure changes to the <tt>XState</tt> cannot be interleaved with those
--   changes to the <tt>WindowSet</tt> without superfluous refreshes, hence
--   breaking composability.
--   
--   This module aims to rectify that situation by drawing attention to it
--   and providing <a>PureX</a>: a pure type with the same monadic

merge :: (Ord a, Num a) => [(a, b)] -> [b] -> [b]

-- | Inverse of <a>split</a>. Merge an indexed list with an unindexed list

--   <li>Merged unindexed list</li>
--   </ul>
--   
--   If the indexed list is empty, this functions consumes the entire
--   unindexed list. If the unindexed list is empty, this function consumes
--   only adjacent indexed elements. For example,
--   <tt>[(10,"ten"),(12,"twelve")]</tt> implies missing unindexed elements
--   and so once <tt>(10,"ten")</tt> is consumed this function concludes.
--   
--   The indexed list is assumed to have been created by <a>split'</a> and
--   not checked for correctness. Indices are assumed to be ascending, i.e.
--   &gt; [(1,"one"),(2,"two"),(4,"four")]
--   
--   The initial and final virtual indices simplify chaining calls to the
--   this function, as as for zippers of lists. Positive values shift the
--   unindexed list towards the tail, as if preceded by that many elements.

-- | A module for handling pixel rectangles: <a>Rectangle</a>.
module XMonad.Util.Rectangle

-- | Rectangle as two points. What those points mean depends on the
--   conversion function.
data PointRectangle a
PointRectangle :: a -> a -> a -> a -> PointRectangle a

-- | Point nearest to the origin.
[point_x1] :: PointRectangle a -> a
[point_y1] :: PointRectangle a -> a

-- | Point furthest from the origin.
[point_x2] :: PointRectangle a -> a
[point_y2] :: PointRectangle a -> a

-- | There are three possible ways to convert rectangles to pixels:
--   
--   <ul>
--   <li>Consider integers as "gaps" between pixels; pixels range from
--   <tt>(N,N+1)</tt>, exclusively: <tt>(0,1)</tt>, <tt>(1,2)</tt>, and so
--   on. This leads to interval ambiguity: whether an integer endpoint
--   contains a pixel depends on which direction the interval approaches
--   the pixel. Consider the adjacent pixels <tt>(0,1)</tt> and
--   <tt>(1,2)</tt> where <tt>1</tt> can refer to either pixel
--   <tt>(0,1)</tt> or pixel <tt>(1,2)</tt>.</li>
--   <li>Consider integers to demarcate the start of each pixel; pixels
--   range from <tt>[N,N+1)</tt>: <tt>[0,1)</tt>, <tt>[1,2)</tt>, and so on
--   - or equivalently: <tt>(N,N+1]</tt>. This is the most flexible
--   coordinate system, and the convention used by the <a>Rectangle</a>
--   type.</li>
--   <li>Consider integers to demarcate the center of each pixel; pixels
--   range from <tt>[N,N+1]</tt>, as though each real-valued coordinate had
--   been rounded (either down or up) to the nearest integers. So each
--   pixel, from zero, is listed as: <tt>[0,0]</tt>, <tt>[1,1]</tt>,
--   <tt>[2,2]</tt>, and so on. Rather than a coordinate system, this
--   considers pixels as row/colum indices. While easiest to reason with,
--   indices are unable to represent zero-dimension rectangles.</li>
--   </ul>
--   
--   Consider pixels as indices. Do not use this on empty rectangles.

coordinatesToRectangle :: PointRectangle Integer -> Rectangle

-- | True if either the <a>rect_width</a> or <a>rect_height</a> fields are
--   zero, i.e. the rectangle has no area.
empty :: Rectangle -> Bool

-- | True if the intersection of the set of points comprising each
--   rectangle is not the empty set. Therefore any rectangle containing the
--   initial points of an empty rectangle will never intersect that
--   rectangle - including the same empty rectangle.
intersects :: Rectangle -> Rectangle -> Bool

-- | True if the first rectangle contains at least all the points of the
--   second rectangle. Any rectangle containing the initial points of an
--   empty rectangle will be a superset of that rectangle - including the
--   same empty rectangle.
supersetOf :: Rectangle -> Rectangle -> Bool

-- | Three layouts: The first, <a>Spiral</a>, is a reimplementation of
--   <a>spiral</a> with, at least to me, more intuitive semantics. The
--   second, <a>Dwindle</a>, is inspired by a similar layout in awesome and
--   produces the same sequence of decreasing window sizes as Spiral but
--   pushes the smallest windows into a screen corner rather than the
--   centre. The third, <a>Squeeze</a> arranges all windows in one row or
--   in one column, with geometrically decreasing sizes.
module XMonad.Layout.Dwindle

-- | Layouts with geometrically decreasing window sizes. <a>Spiral</a> and
--   <a>Dwindle</a> split the screen into a rectangle for the first window
--   and a rectangle for the remaining windows, which is split recursively
--   to lay out these windows. Both layouts alternate between horizontal
--   and vertical splits.
--   
--   In each recursive step, the split <a>Direction2D</a> determines the
--   placement of the remaining windows relative to the current window: to
--   the left, to the right, above or below. The split direction of the
--   first split is determined by the first layout parameter. The split
--   direction of the second step is rotated 90 degrees relative to the
--   first split direction according to the second layout parameter of type
--   <a>Chirality</a>. So, if the first split is <a>R</a> and the second
--   layout parameter is <a>CW</a>, then the second split is
--   <a>Direction2D</a>.
--   
--   For the <a>Spiral</a> layout, the same <a>Chirality</a> is used for
--   computing the split direction of each step from the split direction of
--   the previous step. For example, parameters <a>R</a> and <a>CW</a>
--   produces the direction sequence <a>R</a>, <a>Direction2D</a>,
--   <a>L</a>, <a>U</a>, <a>R</a>, <a>Direction2D</a>, <a>L</a>, <a>U</a>,
--   ...
--   
--   For the <a>Dwindle</a> layout, the <a>Chirality</a> alternates between
--   <a>CW</a> and <a>CCW</a> in each step. For example, parameters
--   <a>U</a> and <a>CCW</a> produce the direction sequence <a>U</a>,
--   <a>L</a>, <a>U</a>, <a>L</a>, ... because <a>L</a> is the <a>CCW</a>
--   rotation of <a>U</a> and <a>U</a> is the <a>CW</a> rotation of
--   <a>L</a>.
--   
--   In each split, the current rectangle is split so that the ratio
--   between the size of the rectangle allocated to the current window and
--   the size of the rectangle allocated to the remaining windows is the
--   third layout parameter. This ratio can be altered using <a>Expand</a>
--   and <a>Shrink</a> messages. The former multiplies the ratio by the
--   fourth layout parameter. The latter divides the ratio by this
--   parameter.
--   
--   <a>Squeeze</a> does not alternate between horizontal and vertical
--   splits and simply splits in the direction given as its first argument.
--   
--   Parameters for both <a>Dwindle</a> and <a>Spiral</a>:
--   
--   <ul>
--   <li>First split direction</li>
--   <li>First split chirality</li>
--   <li>Size ratio between rectangle allocated to current window and
--   rectangle allocated to remaining windows</li>
--   <li>Factor by which the size ratio is changed in response to
--   <a>Expand</a> or <a>Shrink</a> messages</li>
--   </ul>
--   
--   The parameters for <a>Squeeze</a> are the same, except that there is
--   no <a>Chirality</a> parameter.

-- | The default value for this type.
def :: Default a => a

-- | <i>Deprecated: Use def (from Data.Default, and re-exported from
--   XMonad.Actions.Navigation2D) instead.</i>
defaultNavigation2DConfig :: Navigation2DConfig

-- | Encapsulates the navigation strategy
data Navigation2D

-- | Line navigation. To illustrate this navigation strategy, consider
--   navigating to the left from the current window. In this case, we draw
--   a horizontal line through the center of the current window and
--   consider all windows that intersect this horizontal line and whose
--   right boundaries are to the left of the left boundary of the current
--   window. From among these windows, we choose the one with the rightmost
--   right boundary.
lineNavigation :: Navigation2D

-- | Center navigation. Again, consider navigating to the left. Then we
--   consider the cone bounded by the two rays shot at 45-degree angles in
--   north-west and south-west direction from the center of the current
--   window. A window is a candidate to receive the focus if its center
--   lies in this cone. We choose the window whose center has minimum
--   L1-distance from the current window center. The tie breaking strategy
--   for windows with the same distance is a bit complicated (see
--   <a>#Technical_Discussion</a>) but ensures that all windows can be
--   reached and that windows with the same center are traversed in their
--   order in the window stack, that is, in the order <a>focusUp</a> and
--   <a>focusDown</a> would traverse them.
centerNavigation :: Navigation2D

-- | Side navigation. Consider navigating to the right this time. The
--   strategy is to take the line segment forming the right boundary of the
--   current window, and push it to the right until it intersects with at
--   least one other window. Of those windows, one with a point that is the
--   closest to the centre of the line (+1) is selected. This is probably
--   the most intuitive strategy for the tiled layer when using
--   XMonad.Layout.Spacing.
sideNavigation :: Navigation2D

-- | Side navigation with bias. Consider a case where the screen is divided
--   up into three vertical panes; the side panes occupied by one window
--   each and the central pane split across the middle by two windows. By
--   the criteria of side navigation, the two central windows are equally
--   good choices when navigating inwards from one of the side panes. Hence
--   in order to be equitable, symmetric and pleasant to use, different
--   windows are chosen when navigating from different sides. In
--   particular, the lower is chosen when going left and the higher when
--   going right, causing L, L, R, R, L, L, etc to cycle through the four
--   windows clockwise. This is implemented by using a bias of 1.
--   <i>Bias</i> is how many pixels off centre the vertical split can be
--   before this behaviour is lost and the same window chosen every time. A
--   negative bias swaps the preferred window for each direction. A bias of
--   zero disables the behaviour.
sideNavigationWithBias :: Int -> Navigation2D

-- | Hybrid of two modes of navigation, preferring the motions of the
--   first. Use this if you want to fall back on a second strategy whenever
--   the first does not find a candidate window. E.g. <tt>hybridOf
--   lineNavigation centerNavigation</tt> is a good strategy for the
--   floating layer, and <tt>hybridOf sideNavigation centerNavigation</tt>
--   will enable you to take advantage of some of the latter strategy's
--   more interesting motions in the tiled layer.
hybridOf :: Navigation2D -> Navigation2D -> Navigation2D

-- | <i>Deprecated: Use hybridOf with lineNavigation and centerNavigation
--   as arguments.</i>
hybridNavigation :: Navigation2D

-- | Maps each window to a fullscreen rect. This may not be the same
--   rectangle the window maps to under the Full layout or a similar layout
--   if the layout respects statusbar struts. In such cases, it may be
--   better to use <a>singleWindowRect</a>.
fullScreenRect :: Screen -> Window -> X (Maybe Rectangle)

-- | Maps each window to the rectangle it would receive if it was the only
--   window in the layout. Useful, for example, for determining the default
--   rectangle for unmapped windows in a Full layout that respects
--   statusbar struts.
singleWindowRect :: Screen -> Window -> X (Maybe Rectangle)

-- | Switches focus to the closest window in the other layer (floating if
--   the current window is tiled, tiled if the current window is floating).
--   Closest means that the L1-distance between the centers of the windows
--   is minimized.
switchLayer :: X ()

-- | Moves the focus to the next window in the given direction and in the
--   same layer as the current window. The second argument indicates
--   whether navigation should wrap around (e.g., from the left edge of the
--   leftmost screen to the right edge of the rightmost screen).
windowGo :: Direction2D -> Bool -> X ()

-- | Swaps the current window with the next window in the given direction
--   and in the same layer as the current window. (In the floating layer,
--   all that changes for the two windows is their stacking order if
--   they're on the same screen. If they're on different screens, each
--   window is moved to the other window's screen but retains its position
--   and size relative to the screen.) The second argument indicates
--   wrapping (see <a>windowGo</a>).
windowSwap :: Direction2D -> Bool -> X ()

-- | Moves the current window to the next screen in the given direction.
--   The second argument indicates wrapping (see <a>windowGo</a>).
windowToScreen :: Direction2D -> Bool -> X ()

--   directly.
runOrRaise :: String -> Query Bool -> X ()

-- | See <a>runOrRaise</a> and <a>raiseNextMaybe</a>. Version that allows
--   cycling through matches.
runOrRaiseNext :: String -> Query Bool -> X ()

-- | <a>raiseMaybe</a> queries all Windows based on a boolean provided by
--   the user. Currently, there are 3 such useful booleans defined in
--   <a>XMonad.ManageHook</a>: <a>title</a>, <a>resource</a>,
--   <a>className</a>. Each one tests based pretty much as you would think.
--   ManageHook also defines several operators, the most useful of which is
--   (=?). So a useful test might be finding a <tt>Window</tt> whose class
--   is Firefox. Firefox 3 declares the class "Firefox", so you'd want to
--   pass in a boolean like <tt>(className =? "Firefox")</tt>.
--   
--   If the boolean returns <tt>True</tt> on one or more windows, then
--   XMonad will quickly make visible the first result. If no
--   <tt>Window</tt> meets the criteria, then the first argument comes into
--   play.
--   
--   The first argument is an arbitrary IO function which will be executed
--   if the tests fail. This is what enables <a>runOrRaise</a> to use
--   <a>raiseMaybe</a>: it simply runs the desired program if it isn't
--   found. But you don't have to do that. Maybe you want to do nothing if
--   the search fails (the definition of <a>raise</a>), or maybe you want
--   to write to a log file, or call some prompt function, or something
--   crazy like that. This hook gives you that flexibility. You can do some
--   cute things with this hook. Suppose you want to do the same thing for
--   Mutt which you just did for Firefox - but Mutt runs inside a terminal
--   window? No problem: you search for a terminal window calling itself
--   "mutt", and if there isn't you run a terminal with a command to run
--   Mutt! Here's an example (borrowing <tt>runInTerm</tt> from
--   <a>XMonad.Util.Run</a>):
--   
--   <pre>

-- | This module implements a proper way of finding out whether the window
--   is remote or local.
--   
--   Just checking for a hostname and WM_CLIENT_MACHINE being equal is
--   often not enough because the hostname is a changing subject (without
--   any established notification mechanisms), and thus WM_CLIENT_MACHINE
--   and the hostname can diverge even for a local window.
--   
--   This module solves the problem. As soon as there is a new window
--   created, we check the hostname and WM_CLIENT_MACHINE, and then we
--   cache the result into the XMONAD_REMOTE property.
--   
--   Notice that XMonad itself does not know anything about hostnames, nor
--   does it have any dependency on Network.* modules. For this module it
--   is not a problem: you can provide a mean to get the hostname through
--   your config file (see usage). Or, if you don't like the hassle of
--   handling dynamic hostnames (suppose your hostname never changes), it
--   is also fine: this module will fallback to using environment
--   variables.
module XMonad.Util.RemoteWindows

-- | Given a window, tell if it is a local or a remote process. Normally,
--   it checks XMONAD_REMOTE property. If it does not exist (i.e. the
--   manageRemote hook was not deployed in user's config), it falls back to
--   checking environment variables and assuming that hostname never
--   changes.
isLocalWindow :: Window -> X Bool

-- | Use this hook to let XMonad properly track remote/local windows. For
--   example, <tt>manageHook = manageRemote =&lt;&lt; io getHostName</tt>.
manageRemote :: String -> ManageHook

-- | Use this hook if you want to manage XMONAD_REMOTE properties, but
--   don't want to use an external getHostName in your config. That way you
--   are retreating to environment variables.
manageRemoteG :: ManageHook


-- | This module implements a special kind of layout modifier, which when
--   applied to a layout, causes xmonad to stop all non-visible processes.
--   In a way, this is a sledge-hammer for applications that drain power.
--   For example, given a web browser on a stoppable workspace, once the
--   workspace is hidden the web browser will be stopped.
--   
--   Note that the stopped application won't be able to communicate with
--   X11 clipboard. For this, the module actually stops applications after
--   a certain delay, giving a chance for a user to complete copy-paste
--   sequence. By default, the delay equals to 15 seconds, it is
--   configurable via <a>Stoppable</a> constructor.
--   
--   The stoppable modifier prepends a mark (by default equals to
--   "Stoppable") to the layout description (alternatively, you can choose
--   your own mark and use it with <a>Stoppable</a> constructor). The
--   stoppable layout (identified by a mark) spans to multiple workspaces,
--   letting you to create groups of stoppable workspaces that only stop
--   processes when none of the workspaces are visible, and conversely,
--   unfreezing all processes even if one of the stoppable workspaces are
--   visible.
--   
--   To stop the process we use signals, which works for most cases. For
--   processes that tinker with signal handling (debuggers), another
--   (Linux-centric) approach may be used. See
--   <a>https://www.kernel.org/doc/Documentation/cgroups/freezer-subsystem.txt</a>

module XMonad.Actions.Search

-- | Given a browser, a search engine's transformation function, and a
--   search term, perform the requested search in the browser.
search :: Browser -> Site -> Query -> X ()
data SearchEngine
SearchEngine :: Name -> Site -> SearchEngine

-- | Given a base URL, create the <a>SearchEngine</a> that escapes the
--   query and appends it to the base. You can easily define a new engine
--   locally using exported functions without needing to modify
--   <a>XMonad.Actions.Search</a>:
--   
--   <pre>
--   myNewEngine = searchEngine "site" "http://site.com/search="
--   </pre>
--   
--   The important thing is that the site has a interface which accepts the
--   escaped query string as part of the URL. Alas, the exact URL to feed
--   searchEngine varies from site to site, often considerably, so there's
--   no general way to cover this.
--   
--   Generally, examining the resultant URL of a search will allow you to
--   reverse-engineer it if you can't find the necessary URL already
--   described in other projects such as Surfraw.
searchEngine :: Name -> String -> SearchEngine

-- | If your search engine is more complex than this (you may want to
--   identify the kind of input and make the search URL dependent on the
--   input or put the query inside of a URL instead of in the end) you can
--   use the alternative <a>searchEngineF</a> function.
--   
--   <pre>
--   searchFunc :: String -&gt; String
--   searchFunc s | "wiki:"   `isPrefixOf` s = "http://en.wikipedia.org/wiki/" ++ (escape $ tail $ snd $ break (==':') s)
--                | "http://" `isPrefixOf` s = s
--                | otherwise               = (use google) s
--   myNewEngine = searchEngineF "mymulti" searchFunc
--   </pre>
--   
--   <tt>searchFunc</tt> here searches for a word in wikipedia if it has a
--   prefix of "wiki:" (you can use the <a>escape</a> function to escape
--   any forbidden characters), opens an address directly if it starts with
--   "http://" and otherwise uses the provided google search engine. You
--   can use other engines inside of your own through the <a>use</a>
--   function as shown above to make complex searches.
--   
--   The user input will be automatically escaped in search engines created
--   with <a>searchEngine</a>, <a>searchEngineF</a>, however, completely
--   depends on the transformation function passed to it.
searchEngineF :: Name -> Site -> SearchEngine

-- | Like <a>search</a>, but in this case, the string is not specified but
--   grabbed from the user's response to a prompt. Example:
--   
--   <pre>
--   , ((modm, xK_g), promptSearch greenXPConfig google)
--   </pre>
--   
--   This specializes "promptSearchBrowser" by supplying the browser
--   argument as supplied by <a>getBrowser</a> from
--   <a>XMonad.Prompt.Shell</a>.
promptSearch :: XPConfig -> SearchEngine -> X ()

-- | Like <a>search</a>, but for use with the output from a Prompt; it
--   grabs the Prompt's result, passes it to a given searchEngine and opens
--   it in a given browser.
promptSearchBrowser :: XPConfig -> Browser -> SearchEngine -> X ()

-- | Like <a>search</a>, but for use with the X selection; it grabs the
--   selection, passes it to a given searchEngine and opens it in the
--   default browser . Example:
--   
--   <pre>
--   , ((modm .|. shiftMask, xK_g), selectSearch google)
--   </pre>
--   
--   This specializes "selectSearchBrowser" by supplying the browser
--   argument as supplied by <a>getBrowser</a> from
--   <a>XMonad.Prompt.Shell</a>.
selectSearch :: SearchEngine -> X ()

-- | Like <a>search</a>, but for use with the X selection; it grabs the

selectSearchBrowser :: Browser -> SearchEngine -> X ()

-- | The <a>isPrefixOf</a> function takes two lists and returns <a>True</a>
--   iff the first list is a prefix of the second.
--   
--   <pre>
--   &gt;&gt;&gt; "Hello" `isPrefixOf` "Hello World!"
--   True
--   </pre>
--   
--   <pre>
--   &gt;&gt;&gt; "Hello" `isPrefixOf` "Wello Horld!"
--   False
--   </pre>
isPrefixOf :: Eq a => [a] -> [a] -> Bool

-- | Escape the search string so search engines understand it. Only digits
--   and ASCII letters are not encoded. All non ASCII characters which are
--   encoded as UTF8
escape :: String -> String

-- | Given an already defined search engine, extracts its transformation
--   function, making it easy to create compound search engines. For an
--   instance you can use <tt>use google</tt> to get a function which makes
--   the same transformation as the google search engine would.
use :: SearchEngine -> Site

-- | This function wraps up a search engine and creates a new one, which
--   works like the argument, but goes directly to a URL if one is given
--   rather than searching.
--   
--   <pre>
--   myIntelligentGoogleEngine = intelligent google
--   </pre>
--   
--   Now if you search for http://xmonad.org it will directly open in your
--   browser
intelligent :: SearchEngine -> SearchEngine

-- | Connects a few search engines into one. If the search engines' names
--   are "s1", "s2" and "s3", then the resulting engine will use s1 if the
--   query is <tt>s1:word</tt>, s2 if you type <tt>s2:word</tt> and s3 in
--   all other cases.
--   
--   Example:
--   
--   <pre>
--   multiEngine = intelligent (wikipedia !&gt; mathworld !&gt; (prefixAware google))
--   </pre>
--   
--   Now if you type "wiki:Haskell" it will search for "Haskell" in
--   Wikipedia, "mathworld:integral" will search mathworld, and everything
--   else will fall back to google. The use of intelligent will make sure
--   that URLs are opened directly.
(!>) :: SearchEngine -> SearchEngine -> SearchEngine

-- | Makes a search engine prefix-aware. Especially useful together with
--   <a>!&gt;</a>. It will automatically remove the prefix from a query so
--   that you don't end up searching for google:xmonad if google is your
--   fallback engine and you explicitly add the prefix.

-- | This module contains two hooks for the PositionStore (see
--   <a>XMonad.Util.PositionStore</a>) - a ManageHook and an EventHook.
--   
--   The ManageHook can be used to fill the PositionStore with position and
--   size information about new windows. The advantage of using this hook
--   is, that the information is recorded independent of the currently
--   active layout. So the floating shape of the window can later be
--   restored even if it was opened in a tiled layout initially.
--   
--   For windows, that do not request a particular position, a random
--   position will be assigned. This prevents windows from piling up
--   exactly on top of each other.
--   
--   The EventHook makes sure that windows are deleted from the
--   PositionStore when they are closed.

-- | xmonad calls the logHook with every internal state update, which is
--   useful for (among other things) outputting status information to an
--   external status bar program such as xmobar or dzen. DynamicLog
--   provides several drop-in logHooks for this purpose, as well as
--   flexible tools for specifying your own formatting.
module XMonad.Hooks.DynamicLog

-- | Run xmonad with a dzen status bar set to some nice defaults.
--   
--   <pre>
--   main = xmonad =&lt;&lt; dzen myConfig
--   
--   myConfig = def { ... }
--   </pre>
--   
--   The intent is that the above config file should provide a nice status
--   bar with minimal effort.
--   
--   The binding uses the XMonad.Hooks.ManageDocks module to automatically
--   handle screen placement for dzen, and enables 'mod-b' for toggling the
--   menu bar. Please refer to <a>dzenWithFlags</a> function for further
--   documentation.
dzen :: LayoutClass l Window => XConfig l -> IO (XConfig (ModifiedLayout AvoidStruts l))

-- | Run xmonad with a dzen status bar with specified dzen command line

--   
--   <pre>
--   main = xmonad =&lt;&lt; dzenWithFlags flags myConfig
--   
--   myConfig = def { ... }
--   
--   flags = "-e onstart lower -w 800 -h 24 -ta l -fg #a8a3f7 -bg #3f3c6d"
--   </pre>
--   
--   This function can be used to customize the arguments passed to dzen2.
--   e.g changing the default width and height of dzen2.
--   
--   If you wish to customize the status bar format at all, you'll have to
--   use the <a>statusBar</a> function instead.
--   
--   The binding uses the XMonad.Hooks.ManageDocks module to automatically
--   handle screen placement for dzen, and enables 'mod-b' for toggling the
--   menu bar.
--   
--   You should use this function only when the default <a>dzen</a>
--   function does not serve your purpose.

--   
--   At the present time, the current layout and window title are not

-- | Utility functions for simulating independent sets of workspaces on
--   each screen (like dwm's workspace model), using internal tags to
--   distinguish workspaces associated with each screen.
module XMonad.Layout.IndependentScreens
type VirtualWorkspace = WorkspaceId
type PhysicalWorkspace = WorkspaceId
workspaces' :: XConfig l -> [VirtualWorkspace]
withScreens :: ScreenId -> [VirtualWorkspace] -> [PhysicalWorkspace]
onCurrentScreen :: (VirtualWorkspace -> WindowSet -> a) -> PhysicalWorkspace -> WindowSet -> a

-- | This turns a naive pretty-printer into one that is aware of the
--   independent screens. That is, you can write your pretty printer to
--   behave the way you want on virtual workspaces; this function will
--   convert that pretty-printer into one that first filters out physical
--   workspaces on other screens, then converts all the physical workspaces
--   on this screen to their virtual names.
--   
--   For example, if you have handles <tt>hLeft</tt> and <tt>hRight</tt>
--   for bars on the left and right screens, respectively, and <tt>pp</tt>
--   is a pretty-printer function that takes a handle, you could write
--   
--   <pre>
--   logHook = let log screen handle = dynamicLogWithPP . marshallPP screen . pp $ handle
--             in log 0 hLeft &gt;&gt; log 1 hRight
--   </pre>
marshallPP :: ScreenId -> PP -> PP

-- | Take a pretty-printer and turn it into one that only runs when the
--   current workspace is one associated with the given screen. The way
--   this works is a bit hacky, so beware: the <a>ppOutput</a> field of the
--   input will not be invoked if either of the following conditions is
--   met:
--   
--   <ol>
--   <li>The <a>ppSort</a> of the input returns an empty list (when not
--   given one).</li>
--   <li>The <a>ppOrder</a> of the input returns the exact string
--   <tt>"\0"</tt>.</li>
--   </ol>
--   
--   For example, you can use this to create a pipe which tracks the title
--   of the window currently focused on a given screen (even if the screen
--   is not current) by doing something like this:
--   
--   <pre>
--   ppFocus s = whenCurrentOn s def
--       { ppOrder  = \(_:_:title:_) -&gt; [title]
--       , ppOutput = appendFile ("focus" ++ show s) . (++ "\n")
--       }
--   </pre>
--   
--   Sequence a few of these pretty-printers to get a log hook that keeps
--   each screen's title up-to-date.
whenCurrentOn :: ScreenId -> PP -> PP

-- | In case you don't know statically how many screens there will be, you
--   can call this in main before starting xmonad. For example, part of my

--   <pre>
--   main = do
--     nScreens &lt;- countScreens
--     xmonad $ def {
--       ...
--       workspaces = withScreens nScreens (workspaces def),
